In 1990, the Italian government enlisted top engineers to stabilize Pisas famous Leaning Tower. Thered been many attempts during its 800 year history, but computer models revealed the urgency of their situation. The tower would topple if it reached an angle of 5. 44 degrees and it was currently leaning at 5. 5. What gives the tower its infamous tilt? Alex Gendler explores the monument's history.

As an engineer, in constructions that people's lives will be in danger when something goes wrong,
we always calculate the limits until the accident occurs with a safety factor.
Meaning that when the calculations say it is 5. 44, they include the safety factor.
The real number for the accident to occur may be 6 but we will never go that far since we always calculate with this.

Tell me again why this tower is so special? It is a building that was built incorrectly at a time when there were Engineers who knew better. This is like if 300 years from now, someone celebrated a game designed with poor game play and graphics in 2020 when there are far more superior game designers in the world.

Fun fact: every building in the plaza where the leaning tower is is actually leaning. You cant tell simply because the tower is very very bent.
If you watch the Duomo of Pisa alone youll notice!

The interesting thing is, if this didn't happen, modern science probably wouldn't have known the importance of soil in construction. It has handed us a vital lesson

I suggest everyone to have a look at the structures of ancient India to understand how inteligent people used to be even that time

TED-Ed: They projected the tower would topple if it reached an angle of 5. 44 degrees, and it was currently leaning at 5. 5
